Chu Wanzhao, the orphan of the War Clan, is reborn in a desperate situation, flipping the table to refuse being sucked dry of her family's legacy by the Heavenly Realm. Instead of accepting divine rewards, she turns to cultivate the martial slaughter path. After uncovering the shocking truth that the entire family's death in battle was caused by the Heavenly Emperor being possessed and framed by the Demon Lord—revealing that the War Clan's total annihilation back then was never a defeat, but a long-planned betrayal—she joins hands with the Ancient Empress and the Demon Realm Young Master to cut through the Nine Heavens, execute the false emperor, and exact bloody revenge for the three hundred thousand heroic souls.
